I've got a 93 lightning with a 6.0/t56 magnum and a vortech blower running the 2 bar map sensor os for an 03 computer
my tuner has not been able to find a manual trans os that is compatible with the 2 bar map os so he basically tuned the
auto os to where ot will work but I won't be able to use my cruise the way it setup now. Does anyone know of a tune file
for an 03 cumputer that has a manual? I've looked everywhere and have not been able to find one. I was thinking a 4.8/5 speed
might work but I can't find one for that either. Thank you in advance for any help

Why not try the 12212156 file for a dbw corvette with manual trans ( http://www.tunefiledepot.com/calibrations/stock/Chevrolet/2002%20Chevrolet%20Corvette%20Coupe%20Manual%20LS1 %205.7%20Litre%20(12212156).tun ) for a good initial manual trans file then its super easy to do the COS5 upgrade.
